Description

Technical Field

[0001] The utility model relates to the technical field of vulcanized rubber, in particular to a rubber vulcanizing machine for producing rubber products. Background Art

[0002] As we all know, a vulcanizer is a device used to vulcanize various rubber products. It can be divided into three types: electric heating, steam heating and oil heating. It is widely used in various industrial productions, such as rubber soles, basketball inner layers, etc.

[0003] Rubber products are widely used in various aspects of industry and life. Vulcanizers can be used to vulcanize rubber products commonly used in life, such as molded O-rings, button products, pressure cookers and rice cooker sealing gaskets, etc. The existing vulcanizers do not mix rubber and vulcanizers sufficiently during the mixing process, resulting in low vulcanization effect and easy clogging of the discharge barrel during discharging.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a rubber vulcanizing machine for producing rubber products, which has the following beneficial effects:

[0017] The rubber vulcanizer for rubber product production has an annular tube, a stirring rod and a heating rod, and a pump body transports the vulcanizer into the annular tube through a medicine delivery tube in a vulcanizing barrel, and then sprays it through a spray head at the bottom end of the annular tube. The rotating shaft drives the stirring rod, and the stirring rod drives the heating rod to rotate at a uniform speed under the drive of a first motor, thereby ensuring uniform heating of the rubber material. The electric heating wire inside the heating rod generates heat, so that the temperature and pressure inside the vulcanizer body are stably maintained within the range required for rubber vulcanization. The annular spray head arranged at the bottom end of the annular tube makes the vulcanizer spray more evenly, so that the rubber raw material and the vulcanizer are fully and evenly mixed and vulcanized.

[0018] The rubber vulcanizer for rubber product production has spiral conveying blades that are driven by a rotating shaft to rotate and convey. The spiral conveying blades can convey the material in the vulcanizer body from top to bottom in the discharge barrel and discharge it through a discharge pipe on one side, thereby ensuring that the material is in a flowing state and avoiding clogging of the vulcanized material during discharge. The pressure gauge detects the pressure in the vulcanizer body. When the pressure inside the vulcanizer body exceeds a safe value during the vulcanization process, the gas is discharged through the air relief valve to release the internal pressure.
